Synopsis:
Wireless channels have impairments that restrict the range, data rate and the reliability of the wireless transmission. Such examples of the impairments are noise, multi-path fading, adjacent and co- channel interferences, signal blockage and propagation path-loss. Faced with ever increasing demand for user applications and finite bandwidth resources, new and improved technologies should be developed to allow future wireless networks to meet the increasing demands for high data-rate applications.
In this talk I am going to shed lights on three new techniques that can be used in the future generations of wireless communications networks: Cooperative relaying networks, Large MIMO and Spatial modulation.
Cooperative relaying networks are recently introduced and are gaining interest for future generation wireless standards. They have promise to enhance wireless communication capability and provide a new paradigm for the development of efficient bandwidth usage, resulting in a significant increase of the capacity and diversity gain. In cooperative systems, idle nodes (users) are used as relays between the source and the destination.
Large MIMO is a new promising technique that scales up the traditional MIMO by an order of magnitude compared to the current standards. It is a system that uses antenna arrays with a few tens (or even hundreds) antennas, that intravenously serve many tens of user in the same time-frequency-code resource. The basic idea of large MIMO is to reap all the advantages of the traditional MIMO, however in a much greater scale.
Spatial Modulation is an alternative and promising MIMO technique that utilizes the spatial information in a novel fashion. At each time instance, only a single transmit antenna is activated among the set of existing transmit antennas and the activated antenna index is implicitly used to convey information. As compared to other MIMO techniques, spatial modulation is shown to have several advantages among of which are, complete avoidance of inter-channel interference (ICI), relaxed inter-antenna synchronization requirements, low receiver complexity, use of a single RF chain at the transmitter, and enhanced error performance with moderate number of transmit antennas.
